• It may be used for a heater core of a hot water type heating device, may be used for an evaporator / condenser of a cooling device, and may be used for various laminated heat exchangers such as oil filters.
• the core portion is formed by laminating a plurality of core elements in the width direction and the vertical direction of the stacked heat exchanger (the flow direction of the second heat medium) 3 ⁇ 4).
• the core portion may be formed by laminating a plurality of first and second core elements only in the flow direction of the second heat medium of the vessel. Further, a plurality of the first and second core elements may be stacked in the front-rear direction of the stacked heat exchanger (in the flow direction ⁇ of the first heat medium).
• the tube portions are provided on both sides of the core element, but the tube portions are provided only on one side plate of the core element (the first side plate). May be.
• the plurality of flat plate portions are provided at the upstream end and the downstream end in the air flow direction of the side plate.
• the plurality of flat plate portions are provided at any position of the side plate. Is also good.
• two flat plates may be provided near the center of the side plate.
• Fig. 26 and Fig. 27 show the first and second core elements.
• core elements 400 and 500 in which dimples 403 and ribs 503 are formed in the tube portions 402 and 502 of one of the side plates 401 and 501 may be used.
• two intermediate plates 603 and 604 are added to the other side plates 601 and 602 to form two core elements.
• the core element 600 having the tube portions 605, 606, 607s 608 may be used.
• three or more tubes are added to the other side plates 601 and 602. A part may be formed.
• the cross-sectional shapes of the lever and the slit are not limited to the present embodiment, but may be any shapes.
• the louver of the fin plate 2 may be used.
• Shapes such as 25 and slit 26 may be used.
• the heat exchanger according to the present invention is particularly useful as a heat exchanger that exchanges heat between two media such as a radiator, a heater core, an evaporator, and a capacitor mounted on an automobile. .
